Daring Fireball links to two pieces: one arguing that information wants to be free, and the other (the Wikipedia entry on Stewart Brand) arguing that information also wants to be expensive.
I think it is time to set the record straight: information doesn’t want anything. Information is an inanimate good; it has no wants and no desires. People may want information to be free, or expensive, but information itself wants nothing.
Don’t anthropomorphize inanimate objects. They hate it when you do that.
Edited to add: Lawrence points out that I didn’t mention the Pathetic fallacy. Good catch.
